    PI Notifications 2017 R2 U1 Fails to send emails (ATTR35)

    VCampus-METCO

      I upgraded from PI AF Services 2017 SP1 to 2017 R2 Update 1.

      I had configured some notifications to send to the email delivery channel and these worked fine before the upgrade.

      Since the upgrade I get the error

           "System.Net.Mail.SmtpException: Error in processing. The server response was: 4.4.62 Mail sent to the wrong Office 365 region. ATTR35. For more information please go to https://go.microsoft.com/fwlink/?linkid=865268. "

       

      Any ideas as to what the problem is here? There is a Microsoft article at the link provided but it doesn't mean much to me. I find it strange that it worked before the upgrade and not after - the SMTP server has not changed. I tried all 3 methods of authentication (windows, anonymous, basic) with the same result.
